A new bc-upgrade step in the intake pipeline invokes a bash script to get the commit hash of the latest BC (or snapshot if no BC is available yet) from https://docs.elastic.dev/release/stack/release-api#future-releases for the current branch and runs BWC / upgrade tests from this commit to the HEAD commit of the current branch.
If no matching BC / snapshot exists, the upgrade tests are skipped.
